I assume an automatic box? Auto boxes with a sports/economy modes feature will have a button or lever somewhere with E and S. (Uusally on or near the main shift lever.) If you don't have a button or similar, what makes you think that your car has this feature? If an auto box takes long time to shift, its usually because you have your foot too hard on the loud pedal.. Try easing off the gas and the box should shift up.
